TEMPORARY BINDER OB LOOSE-SHEET HOLDER.

Specification of Letters Patent. Patented Dec. 28, 1909.

Application filed April 18, 1907. Serial No. 368,999.

To all whom "it may concern:

Be it known that. I, IIARRY F. a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Temporary Binders or Loose-Sheet. Holders, of which the following is a specification.

This invention relates to Bosnon c,

improvements in My present invention is a modification of and in some respects an improvement upon my temporary binders or loose sheet hol ers illustrated in my applications for Letters Patent filed July 15, 1904, Serial No. 216,663, and August 5, 1901, X0. 219,624.

The main objects of this invention are,j First, to rovide an improved temporary l l l l hinder or oose sheet. holder which is light. in weight. simple in structure. and at the same time very durable and strong. Second, to provide an improved temporary hinder or loose sheet holder which is very economical to produce and at the same time a desirable structure and one which is convenient and easy to use, holding the leaves in a very desirable and effective manner.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow. l accomplish the objects of my invention by the devices and means described in the t following specification. The invention clearly defined and pointed out in the claims. structure embodying the features of my invention is clearly illustrated in the ac eompanying drawing, forming a part of this t Figure 1 is an inside-detail of a structure l embodying the features of my invention, the covers being open, one of the clamping bars being shown in longitudinal section and t ortions of the other being broken awato 3 show the structural details, a number of 1 sheets or leaves being shown in conventional form therein. Fig. 2 is tion taken on a hue corres 2-2 of Fig. '1, with the bin a longitudinal secending to line] er in its closed v1 so position, a number of sheets or leaves being shown in conventional form therein. Fig. 3 is a longitudinal section through one of the clampin bars taken on a line corresponding to ine 33 of Fig. 1. Fig. 1 is an enlarged detail section showing the structural details of the clamping bar, the same being taken on a line corresponding to line -'l4 of Fig. 1. detail transverse section taken on a line corresponding to line 5-5 of Fig. 1. Fig. 6 is a detail inside plan, partially in section, of a modified constructon, one adjusting screw only being illustrated.

In the drawing similar reference characters refer to similar parts throughout the several views. 7

Referrin to the drawings, the covers 1 are prefera ly chambered as illustrated, for the sake of strength and lightness. 1 provide a pair of leaf clamping bars or jaws 2, which are chambered to receive the binder adjustin mechanism. These bars are preferably formed of metal shells 3 and end blocks 4.. The sheets or leaves 5 are clamped between these bars, substantially in the same manner as in the structures of my applications for patents hereinbefore referred to. The clampin bars are connected by flexible binding cors arranged through suitable openings 7 provided therefor in the inner or clamping faces Arranged longitudinally within bars are threaded shafts or mg cords. the clamping screws 9. the ends of these shafts being oppositely threaded. The shafts are provided with suitable journals at each end, the end blocks 4 of the clamping bars being refer ably arranged to form bearings there or.

1 preferably arrange an adjusting shaft in each of the clam ing bars, as y this means the scope of tlie adjustment is considerably increased. A satisfactory structure may, however, be reduced y providin only one of the c amping bars with an ad usting screw, the binding cords being Fig. 5 is a. large 6', the binding cords being .preferably provided with inwardly pro Jecting rigid hinge members 12, which are preferably pivoted u on the screw shafts 9. It is obvious'that in ependent pivots might be provided, but I by this means secure a very simple structure and at the same time a very strong one.

The clamping bars are slotted transversely as at 13 to receive the hinge members 12, sothat the clamping bars and covers may move independently of each other in the opening or closing of the book.

The clamping bars are of such shape that by means of the ri id hinge members and the pivotal connectlonsof the bars thereto the clamping bars are held in alinement with the covers, so that while a very free and independent movement is secured in open ing and closin the book or in adjusting the leaves in the c amping bars, the structure is attractive in appearance'and the parts are always held in their proper relation Whether the binder be opened or closed.

I have illustrated and described my present improvements in detail in the form preferred by me on account of structural simplicity and economy and convenience in use.

am, however, aware that it is capable of great modification in structural details and desire to be understood as claiming the same specifically as illustrated, as Well as broadly.

Having thus described my invention, what i I claim as new and desire to secure by Letters Patent, is:
